What can be used to help thyroid disease? I've tried all sorts of fish and it doesn't help. It is hypo not hyper.

Thyroid testing. The TSH is the most commonly ordered thyroid blood test, but additional tests are required to determine if the thyroid is functioning optimally. The two thyroid hormones are T4 and T3 (liothyronine). Reverse T3 (liothyronine) is also a hormone, but block action of T3 (liothyronine). See your doctor or endocrinologist for a complete evaluation and exam if concerned about thyroid function.
